Did anyone ever find a fix for this? I live in Anchorage, Alaska and drive a '15 Silverado. Every time my truck sits out overnight when it's colder than 10 degrees, I have this issue the next day. Since this does seem to be a relatively common issue, I contacted my dealership service to see if they'd had any other complaints of the same problem. They said they had not, which was surprising considering the colder temps up here. I had read on another forum that replacing the radio unit may fix the problem, but I was hoping to get some confirmation on that before I spend the money to do that.
